Retaining Rings, which are available in several types and various sizes, are used to fasten assemblies on shafts or inside housings and bores. The ring installs into a groove, thereby creating a shoulder that will retain the assembly. They function with a minimal amount of surface prep to either the shaft or the housing.

These are only a few of the applications in which Retaining Rings are used, often being more efficient and cost-effective than traditional fasteners such as cotter pins, bolts, nuts, washers, screws and more.

Century Spring now stocks three types of Retaining Rings:

  1. ER Series: External
  2. IR Series: Internal
  3. E Series: External Reinforced

These are all available in carbon spring steel (SAE 1060-1090).
